s An object of my invention is to provide a novel type of device for changing liquid fuel into a vapor prior to the burning of thefuel.,

The device is designed to cause the liquid fuel to flow over a series of heated plates and ila) toV drop from one plate to another untilall 3o izing device.

The device directs the vapor toward one end where it is burned. `A further object of my invention is to pro- V vide a device of the type described which may 15 be quickly assembled and placed in a bur-ner without the necessity of fastening the device inlace.

It should be noted that the burner is divided into two compartments A and B, and that these are partially separated from .each other by an upwardly-extending rib 4. yA curved tongue 5 extends downwardly into the compartment B from the top of the burner. vvAn air pipe 'leads into the compartment B,'and the compartment A is providedwi th a large opening 7 :through whichtheburning'vapor 5 passes.

VThe plates 9 and 10'are perforated, and

the perforations of 'one' plate are staggered with respect to those of the other .in order Vto prevent lthe dropping ofthe oil directly from the to plateto thel bottom plate. The top' plate 9 Figure 1.

The stepped arrangement of the plates 9, ,A l0and 11 provide openings at the lett-hand side of the vaporizing device through which the vapor passes. This vapor isl instantly ignited by the iame, and this ame passes through the o enin 7 and on into the furnace 1. This ame eeps the plates hot, and thus provides a simple automatic means for forming additional vapor so long as the device functions.

n Figure 3, T show a fuel pipe 26 controlled by a valve 27. The pipe 26 communicates with the pipe 23. The pipe 26 isA supported by a stub pipe 28 that 1s carried by the burner` 2. The pipe 28 is not designed to carry fuel, but is merely a support.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of \va rious changes, and T'reserve the right to employ such changes as may come within the scope of the invention as claimed.
